Embodiment Construction

[0012] Below in conjunction with embodiment, the present invention will be further described.

[0013] The breeding method flow process of the present embodiment is the same as figure 1 .

[0014] In the early season of 2008 (mid March to late July), F 1 Substitute seeds; plant F in late season (mid-July-early November) 1 , F 1 The seed coats of the plants are all black, and the seeds are mixed when mature. Planting F in Liuzhou in early season 2009 2 At the maturity stage, 38 excellent individual plants with dark black seed coats were selected, 10 non-waxy individual plants were eliminated by indoor rice quality inspection, and 28 excellent individual plants with dark black seed coats were retained. 2009 Late Season Planting F 3 , Select 20 excellent individual plants with dark black seed coats with excellent agronomic properties, eliminate 10 non-waxy individual plants through indoor rice quality testing, and keep 15 excellent individual plants with dark black seed coa...

Abstract

The invention relates to a method for selectively breeding black glutinous rice. The method comprises the following detailed steps of: (1) hybridizing a black glutinous rice variety with a red glutinous rice variety to obtain an F1 generation, wherein all the seed husks of the F1 generation seeds are black; sowing the F1 generation to obtain an F2 generation; (2) sowing the F2 generation and separating a plant with black seed husks and a plant with white seed husks from the F2 generation; sowing plant seeds with excellent agronomic characters, deep black seed husks and glutinous endosperm; carrying out selfing for 6-8 generations to obtain the required variety. The rice bred by the method is good in glutinous property and excellent in growth vigour after being sown in large lands, the stems are thick and strong, the coarse rice is black, and the yield of the rice bred by the method is equivalent to that of the current high-yield white glutinous rice.

Description

technical field [0001] The invention relates to a method for breeding crops, in particular to a method for breeding glutinous rice with black seed coat. Background technique [0002] Black glutinous rice has a higher content of protein, mineral elements and vitamins than ordinary glutinous rice, especially the inorganic salts such as manganese, zinc, copper, calcium, phosphorus, potassium, magnesium, iron, and zinc contained in black glutinous rice are 1- 3 times, it also contains special ingredients such as vitamin C, chlorophyll, anthocyanin, β-carotene and cardiac glycosides that ordinary rice lacks, so it is more nutritious than ordinary glutinous rice, and has good diet and health effects. Black glutinous rice pigment is also a natural pigment, non-toxic, and maintains a variety of nutrients rich in plants, and can be used as a food coloring agent. [0003] At present, the main varieties of black glutinous rice are still the local varieties of the last century. The var...
